example, the wedges may be driven in between.

10 the sleepers progressively in the direction of the rails in such a way that always a row of wedges is driven in series in the rail direction. Preferably, the individual wedges are simply driven into the ballast in the consolidation of already l laid rails without the ballast being taken up.

In many cases it may be advantageous to apply the wedge several times in succession at the same point after the ballast has fallen under gravity into the hole already made in the ballast by the When the wedges have been used, or even without using them, wide plates which may advantageously be rounded somewhat on the underside may be used to stamp the ballast firm, the wide plates being likewise subjected to the 25 action of a mechanical ram device.

The device for carrying out the invention consists accordingly of a wedge, the side surfaces of which are substantially spear-shaped, that is to say, its rate of increase of cross-section decreases irom the bottom upwards. The lower edge of the wedge can advantageously be toothed or corrugated and for example in such a Way that the middle part extends considerably below the lower edge of the side parts. The length of the wedge may be equal to the depth of the bed below the sleepers including the depth of the sleepers themselves, the thickness of the wedge with sleepers laid at intervalsfof about 30 cm. being advantageously to 15 cm. and the 40 length of the wedge being 30 to 40 cm. The wedge may be provided with transverse ribs by which the bed material may be subjected just before the end of the driving in of the wedge to particularly intensive packing in the plane in 5 which the sleepers lie. The individual wedges are advantageously connected to a mechanical ram device, the ram device sliding up or down on a rod or the like which is rigid with the wedge.

(Cil. 164-13) The invention is illustrated by way of example in the accompanying drawing, in which Figure 1 shows a longitudinal section through a bed on which sleepers and rails rest, and shows a number of wedges according to the invention in dif- 5 ferent positions.

Figure 2 shows a plan of an arrangement according to Figure 1 with one rail.

Figure 3 shows a side View of a wedge.

Figure 4 shows a Wedge with a ram device, and 10 Figure 5 shows a consolidating device.

In the drawing a indicates subsoil, b a bed consisting for example of broken stone, c sleepers,` d a rail, e a wedge on which a rod is formed or xed; g are two lateral spikes and h a central spike on the wedge,i is a ram device furnished with handles i which can be raised mechanically for example by means of an explosion of fuel and which, after being raised to a predetermined height, drops back on to the wedge. 1c, indicated 2O in do-tted lines in Figure 1, are enlargements which lead to increased lateral pressure being exerted when the wedges are driven into the top layer. This arrangement is particularly advantageous when the wedge is to be driven down below the lower edge of the sleeper. m are eyes arranged on the wedgesto which chains h are attached and by means of which the wedge is pulled out of the bed after it has been driven in and by which the wedge can be taken bodily away from the ram device. The thickness of the wedge shown in the drawing is about 10-12 cm., the length about 30 to 4Q cm. and the height about 50 to 60 cm. In Figure 5, there is shown a plate o which can likewise be connected by the 35 rod f to a mechanical ram device.

I claim:

An implement for use in consolidating a permanent way bed having a head portion of rectangular cross-section with a major and a minor dimension and with the elongated side faces of said 4head diverging upwardly from the lower edge thereof, the lower edge of said head having longitudinally disposed teeth formed thereon,

the central tooth being of greater depth than and projecting downwardly beyond the remaining teeth.
